Edible Garden Mushrooms: What's Safe To Pick?

what garden mushrooms are ediable

Mushrooms are a common sight in gardens, particularly during the rainy season. While they are often seen as intriguing or mysterious, they are essentially the sexual organs of fungi. They play a crucial role in breaking down organic matter and contributing to nutrient cycling, indicating a healthy soil ecosystem. However, caution is necessary, as many garden mushrooms are toxic and can cause severe health complications if ingested. Determining which mushrooms are edible is challenging, and even experts recommend against consuming wild mushrooms unless they are correctly identified. While some mushrooms, like the field mushroom, fairy ring mushroom, ringless honey mushroom, and puffball mushroom, are edible, others like the Amanita and stinkhorn can be poisonous. Therefore, it is crucial to correctly identify mushrooms before consuming them and always consult with experts.

How to identify edible mushrooms

Identifying edible mushrooms can be a challenging and sometimes dangerous task. It is recommended to consult an expert or join a local mycological group to learn more about foraging for edible mushrooms. However, here are some tips to help you identify edible mushrooms:

General Guidelines

As a general rule, choose mushrooms with tan, brown, or white caps and stems, and avoid those with red caps or stems. Edible mushrooms typically have brown or tan gills, while mushrooms with white gills are often deadly. Avoid mushrooms with scales on the cap or a ring around the stem. Additionally, always choose mushrooms that are pure white inside; if they are yellow or brown inside, they are no longer edible.

Specific Mushroom Types

Some specific types of mushrooms that are generally considered edible include:

  • Hedgehog mushrooms: These mushrooms have a distinctive shape that resembles a lion's mane or a pompom. They are often found growing on hardwood trees, such as beech trees, in late summer and fall.
  • Maitake mushrooms (Grifola frondosa): Also known as "hen of the woods" or "sheep's head," these mushrooms grow at the base of hardwood trees like oaks.
  • Morels: Morels are found in most states, except Florida and Arizona, which are too hot and arid. They thrive in moist areas and grow on specific tree types, including ash, tulip, oak, and beech. Look for their iconic honeycomb-like or corrugated caps above white stems.
  • Lobster mushrooms: Found commonly in the Pacific Northwest, these are not actually mushrooms but a fungus that grows on other mushrooms. They are distinct due to their hard red to orange exterior and white interior, resembling a lobster.
  • Giant puffball mushrooms: These mushrooms are large and orb-shaped, with a white exterior and interior. They do not have any gills, and if the interior is yellow or green, they are past their edible phase.

Additional Tips

When foraging for mushrooms, it is important to take two baskets: one for mushrooms you are confident are edible and another for those you are uncertain about. Always consult an expert or a local mycological group if you are unsure about a mushroom's edibility. Additionally, consider purchasing a mushroom field guide specific to your region to help you identify different mushrooms. Remember, do not ingest a mushroom unless you are 100% sure of its edibility.

Where to find edible mushrooms

If you're looking to find edible mushrooms, there are a few things to keep in mind. Firstly, it's important to only consume mushrooms that have been positively identified as edible; if you're unsure, it's best to leave them alone. Secondly, it's helpful to know what types of mushrooms you're looking for and where they typically grow. Some common edible mushrooms include Morel, Chanterelle, Oyster, Puffballs, and Coral Fungus. These mushrooms can often be found in wooded areas, especially during the fall season after a large rainfall.

When foraging for mushrooms, it's a good idea to check with local resources or experts to find out what species are native to your area. For example, if you're in New Zealand, you can use iNaturalist.nz to identify the types of mushrooms that grow in your specific region. In addition, joining local groups or forums, such as the Facebook group "Mushroom hunting New Zealand", can provide valuable insights and tips from experienced foragers.

Urban areas can also be good places to find edible mushrooms. Mutualistic fungi, for example, are often found near older, more established trees in cities. So, if you're living in a city, keep an eye out for mushrooms in parks or near large, shady trees. However, it's important to be mindful of local laws and regulations regarding foraging in urban spaces.

Lastly, don't be afraid to ask for help. Foraging for wild mushrooms can be dangerous, and it's easy to mistake a poisonous mushroom for an edible one. Consider reaching out to experienced foragers or experts in your community, or join a mushroom foraging workshop to learn more about identification and safe harvesting practices. Remember, always forage responsibly and sustainably, leaving some behind for the next forager and the ecosystem.

What are the risks of eating garden mushrooms?

Consuming garden mushrooms carries several risks, as many mushrooms are poisonous and can cause severe illness or even death. It is critical to only forage for mushrooms with someone highly experienced in identifying both edible and poisonous varieties. Even mushrooms that are typically edible may be contaminated with bacteria or mold and become unsafe to eat.

Mushroom poisoning typically occurs about eight hours after ingestion, when the toxins are absorbed in the intestines. This means that by the time symptoms appear, it may be too late to pump the stomach, making mushroom poisoning difficult to treat. The death cap mushroom (Amanita phalloides) is one of the most poisonous mushrooms in the world and is responsible for the majority of mushroom-related deaths. It grows in many countries and can be found in gardens. Its symptoms include liver and kidney damage, and death can occur within 48 hours of ingestion. Other highly poisonous mushrooms include the autumn skullcap (Galerina marginata), also known as the "deadly Galerina," and the destroying angel (Amanita ocreata), which resembles edible true morels.

Even handling mushrooms can carry risks, as some people have reported becoming ill after picking mushrooms with their bare hands. It is always advisable to wear gloves when handling mushrooms and to wash your hands thoroughly afterward. Additionally, it is crucial to keep young children and pets away from mushrooms, as they may be inclined to put things in their mouths and could accidentally ingest poisonous mushrooms.

While some mushrooms are edible when properly identified and prepared, it is essential to exercise extreme caution. If you are unsure about the identity of a mushroom, it is best to leave it alone. It is also recommended to cook all wild mushrooms before consuming them, as only a few are safe to eat raw.

What are the benefits of eating mushrooms?

Mushrooms are a type of fungus, often considered a vegetable, and are native to North America and Europe. They are known for their delicate flavour and meaty texture, and are widely consumed for their health benefits.

Mushrooms are low in calories and rich in disease-fighting nutrients, vitamins, and minerals. They are also a source of vitamin D, which is important for bone and immune health, and can be hard to obtain from food sources. Mushrooms are also rich in B vitamins, which support neurotransmitter function, and antioxidants, which prevent or slow cellular damage.

Research suggests that eating mushrooms may reduce the risk of developing mild cognitive impairment (MCI) by up to 50%. MCI is often a precursor to Alzheimer's disease, and studies indicate that mushrooms may help protect against this and other neurodegenerative diseases such as Parkinson's.

Mushrooms are also a source of prebiotics, which stimulate the growth of healthy bacteria in the gut. They are also rich in polysaccharides, which pass through the stomach unchanged and can improve insulin resistance and GI health.

When foraging for wild mushrooms, it is important to be cautious as many mushrooms that are poisonous closely resemble edible varieties. It is recommended to only forage with someone highly experienced in identifying both edible and poisonous mushrooms.

How to prepare and cook garden mushrooms

It is important to be cautious when consuming edible mushrooms and to only eat mushrooms that have been harvested with an expert trained in identifying them. Many mushrooms have poisonous look-alikes, and consuming them can pose serious health risks.

When preparing garden mushrooms, it is recommended to avoid washing them, as this can affect their texture and colour. Instead, wipe off any dirt with a damp paper towel. Mushrooms should also be salted at the end of cooking, as salt draws out moisture and can make them mushy.

To cook garden mushrooms, heat a dry pan to a medium-high heat. Add enough cooking fat, such as olive oil, coconut oil, or butter, to generously cover the bottom of the pan. Use a wide skillet to avoid overcrowding the mushrooms, which can cause them to steam instead of brown. Cut the mushrooms into similar-sized pieces and spread them out in a single layer in the pan.

Let the mushrooms cook without stirring until they start to brown. Then, add salt and pepper, and any desired aromatics, such as fresh thyme, rosemary, or sage. For extra flavour, stir in butter, garlic, fresh lemon zest, and lemon juice to create a light buttery sauce.

Some popular ways to cook garden mushrooms include sautéing, roasting, and stir-frying. Oyster mushrooms, for example, are delicious when added to stir-fries, sautés, grain dishes, and soups.
